Nick Coghlan added the comment: The new porting note doesn't quite capture all the subtleties of the situation, but should be sufficient for folks to get any affected custom metaclasses working again (since the key is to avoid passing those parameters up to type.__new__).
I also added a note about the fact that __init_subclass__ implementations don't have access to the metaclass hint, but can retrieve the actual metaclass based on the passed in class object. ---------- resolution: -> fixed stage: needs patch -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27366> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
